A coupling sleeve (1) for a hydraulic coupling to a pressure medium line, for a coupling with a coupling plug (2), having a housing (3) and a sealing unit (4). The housing (3) has a flow channel (5) for a pressure medium and a coupling axis A. The sealing unit (4) includes a sleeve body (6), a pressure sleeve (7), and a valve tappet (8). The sealing unit (4) delimits part of the flow channel (5), the valve tappet (8) is held on the sleeve body (6) and is arranged in the flow channel (5). The pressure sleeve (7) encloses the valve tappet (8). The pressure sleeve (7) can be displaced along the coupling axis A and is held between a closing position, in which the flow channel (5) is locked, and an opening position, in which the flow channel (5) is unlocked. The pressure sleeve (7) is loaded by a pressure spring (10) in the closing direction. A coupling force must be applied by a user to produce a positive coupling to a coupling plug (2).
A coupling sleeve for a hydraulic coupling on a pressure medium line to produce a form-fit coupling to a coupling plug, comprising, a housing and a sealing unit, wherein the housing has a flow channel for a pressure medium and defining a coupling axis, wherein the sealing unit comprises a sleeve body, a pressure sleeve, and a valve tappet, the sealing unit delimits part of the flow channel, the valve tappet is held on the sleeve body via a tappet guide in such a way that the valve tappet is arranged in the flow channel, the pressure sleeve surrounds the valve tappet, the pressure sleeve is displaced along the coupling axis and is held between a closing position, in which the flow channel is closed off by the pressure sleeve, and an opening position, in which the flow channel is opened by the pressure sleeve, the pressure sleeve is loaded by a pressure spring acting in the direction of the closing position, and a coupling force must be applied to produce a positive coupling of the coupling sleeve to the coupling plug,
